High-Temperature Furnaces with SiC Rod Heating up to 1600 °C

Furnace chamber with high-quality fiber materials and SiC heating rods on both sides of the furnace

Saggars with top lid

Over-temperature limiter

These powerful laboratory muffle furnaces are available for temperatures up to 1400 °C, 1500 °C, 1550 °C or 1600 °C. The durability of the SiC rods in periodic use, in combination with their high heating speed, make these high-temperature furnaces to all-rounders in the laboratory. Heating times of 40 minutes to 1400 °C can be achieved, depending on the furnace model and the conditions of use.

Tmax 1400 °C, 1500 °C, 1550 °C or 1600 °C

Working temperature 1500 °C (for high-temperature furnaces HTC ../16), increased wear and tear must be expected in case of working at higher temperatures

Saggars with top lid

Over-temperature limiter

Designed as tabletop models, these compact high-temperature furnaces have a variety of advantages. The first-class workmanship using high-quality materials, combined with ease of operation, make these furnaces all-rounders in research and the laboratory. These high-temperature furnaces are also perfectly suited for the sintering of technical ceramics, such as zirconium oxide dental bridges.

High-Temperature Bottom Loading Furnaces up to 1700 °C

LHT 16/17 LB

High-temperature furnace LHT 02/17 LB with a set of saggars

Electrically driven lift-bottom

Saggar

The electrically driven lift-bottom considerably allows for proper charging of the high-temperature furnaces LHT/LB. The heating all around the cylindrical furnace chamber provides for an opitimal temperature uniformity. For high-temperature furnace LHT 02/17 LB the charge can be placed in charge saggars made of technical ceramics. Up to three charge saggars can be stacked on top of each other resulting in a high productivity. Due to its volume the high-temperature furnace LHT 16/17 LB can also be used for applications in production.

High-Temperature Furnaces with Scale for Determination of Combustion Loss and Thermogravimetric Analysis (TGA)

High-temperature furnace LHT 04/16 SW with scale for measuring weight reduction during annealing and with gas supply system

Software for documentation of the temperature curve and combustion loss using a PC

These high-temperature furnaces were specially developed to determine combustion loss during annealing and for thermogravimetric analysis (TGA) in the lab. The complete system consists of the high-temperature furnace for 1600 °C or 1750 °C, a table frame, precision scale with feedthroughs into the furnace and powerful software for recording both the temperature curve and the weight loss over time.

Due to their solid construction and compact stand-alone design, these high-temperature furnaces are perfect for processes in the laboratory where the highest precision is needed. Oustanding temperature uniformity and practical details set unbeatable quality benchmarks. For configuration for your processes, these furnaces can be extended with extras from our extensive option list.

Tmax 1600 °C, 1750 °C, or 1800 °C

Recommended working temperature 1750 °C (for models HT ../18), increased wear and tear must be expected in case of working at higher temperatures

Dual shell housing with fan cooling for low shell temperatures

Heating from both sides via molybdenum disilicide heating elements

High-quality fiber insulation backed by special insulation

Side insulation constructed with tongue and groove blocks provides for low heat loss to the outside

Long-life roof insulation with special suspension

Chain-guided parallel swivel door for defined opening and closing of the door

Additional equipment

Uncontrolled or controlled cooling system with frequency-controlled cooling fan and motor-driven exhaust air flap

Furnace in DB design featuring fresh air preheating, exhaust gas ventilation and an extensive safety package for debinding and sintering in one process, i. e. without transfering the material from the debinding furnace to the sintering furnace

Stainless steel exhaust gas top hats

Special heating elements for zirconia sintering provide for longer service life with respect to chemical interaction between charge and heating elements

High-Temperature Furnaces with SiC Rod Heating up to 1550 °C

Vertically mounted SiC rods and optional perforated air inlet tubes of the debinding system in a high-temperature furnace

Exhaust air flap and charge thermocouple including a stand as additional equipment

The high-temperature furnaces HTC 16/16 - HTC 450/16 are heated by vertically hung SiC rods, which makes them especially suitable for sintering processes up to a maximum operating temperature of 1550 °C. For some processes, e.g. for sintering zirconium oxide, the absence of interactivity between the charge and the SiC rods, these models are more suitable than the alternatives heated with molybdenum disilicide elements. The basic construction of these furnaces make them comparable with the already familiar models in the HT product line and they can be upgraded with the same additional equipment.
